摘要：

The electron donor-acceptor（EDA）association constants for the reaction of poly（N-vinylcarbazole）(PVK)samples,prepared under three conditions respectively,or their model compound,N-ethenylcarbazole（NECA）,as a donor,and polynitrofluotenone as an acceptor and the molar ab-sorption coefficients of their products have been determined.By analysis ofH NMR of PVK quan-titatively,the isotactic sequence’s percentage Xis estimated.The association constants K may begiven byK=KX+KX,where the subscripts 1 and 2 denote the isotactic and syndiotactic sequenceof the polymer respectively.From the principle of spectral analyses has been deduced the followingrelationship:K=KX6ε+KXε,and estimated the values for K,K,εand ε,where e is the molarabsorption coefficient.
